[CentOS] Question regarding hardened-php

Hi all,

Please forgive what may be an OT question:

I'm considering using hardened php and am interested in any comments
which may be offered regarding hardened php and CentOS5.

For reference:
http://www.hardened-php.net/hardening_patch.14.html

Is hardened php available as an RPM from any of our fine CentOS
repositories?  If not, I'd feel less inclined to use it as it affects
core areas of the distro.

Thanks in advance for any suggestions or comments,

~Ray
